Abstract
The detection of cycle slips and outliers in single-frequency carrier phase data, or any other type of un-expected changes in the single-frequency carrier phase measurements of the GNSS, is one of the major data preprocessing problems that needs to be addressed, especially single-frequency receivers account for most of the market share and GNSS carrier phase data are used for real-time applications that require reliable position results. In this contribution the improved RKF (Robust Kalman Filter) is designed to detect cycle slips or unexpected changes when single-frequency carrier phase is interfered by small outliers, in order to improve the cycle slip detection success rates. Real BDS single-frequency data have been used to test and evaluate the algorithm, where the simulation results indicate that the improved RKF has a higher cycle slip detection success rate than the RKF when observations are interfered by small outliers, proving the efficiency of the algorithm proposed in this paper.
